DESCRIPTION
The A7142 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving 2A load with excellent line and load regulation. These devices are available in fixed output voltages of 5V and an adjustable output versions.
Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation, and a fixed-frequency oscillator. The A7142 series operates at a switching frequency of 150KHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators.
Some features include a guaranteed ±4 tolerance on output voltage under specified input voltage and output load conditions, and ±15 on the oscillator frequency. External shutdown is included, featuring typically 50μA standby current. The output switch includes cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions. The oscillator frequency reduces in the event of an output short or an overload which causes the regulated output voltage to drop approximately 40 from the nominal output voltage.
The A7142 is available in SOP8 and PSOP8 packages.
